"It's a win-win situation for us, we get a chance to really develop and expand and for them to get fit, to enjoy an Olympic facility and to come back.
"We are going to be here five days a week, we are going to have a third of a floor for five days of the week and we have real plans to work with a School of Excellence with higher elite athletes as well," said Barry.
Although boxing has always been Barry's first love, the initiative is much more than a one sport event. It aims to promote healthy eating and living as figures from the National Health Service show an increasing amount of obesity in children.
The McGuigan family are all involved in the academy and are encouraging other families to come on board and to box their way to health.
Event organiser Barry Walpole told UTV: "The McGuigan's do it as a team.
"I am an adopted member of the McGuigan family - but I have been working for them for the last two years so it's been, in terms of getting families down here, that's our main [goal], because everything starts at home, whether it is activity or good habits or bad habits."
